whats better the walboro 392 plus 2micron and bigline or a fass system 150gph with filters??? can the big line be used with the fass?? I have an o5 with the smarty, rokk timing sensor, afe stage II, SB con ofe clutch, getting 50-90hp injectors and probally a tst r49 or a quad stack xzt, then a new turbo... silver bullet 62 or something along those lines..... just want to have plenty of towing guts and some fun power....

 

I've had the fass high pressure pump, and the Glacier 392 with big line and the 2mk filter. They are both very nice in terms of quality and performance. I prefer the Glacier system because of it's compact size and ease of installation. I ran the Fass at 21 psi which dropped to about 17 under load. The Glacier runs at 42 psi which drops to 32 under load. I noticed no power difference when I swapped from one to the other. There isn't any reason why glacier's big line couldn't be used with the fass system.

 

did you remove your factory fuel filter housing?
